It provides with a complete set of equations describing the  evolution of matter and curvature fluctuations for a multi-fluid  cosmological medium. It also deals with a  specific model of a radiation-dust fluid  universe described by  barotropic equations  of state where the perturbation equations are applied  around a  background  solution of a specific toy model of gravity and looks at exact solutions   for scales  much  smaller and much larger than the Hubble radius.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844314045\"\u003e\u003ch3\u003eA study of the formation of cosmic structure in a modified theory of gravity\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844314045","offer_id":39495922581597,"sku":"9783844314045","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/375623ae-0be4-45a1-ab74-12ffefd8db7c.jpg?v=1757825725","url":"https:\/\/shop.autorenwelt.de\/en\/products\/covariant-perturbations-in-fr-gravity-of-multi-fluid-cosmologies-von-amare-abebe","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
